Quality Control of Wire Bonding

Wire Bonding is used for fabrication of most advanced electronic parts, such as high densely packaged Hybrid IC and MCM.
Before wire bonding is carried out, a work will be preheated in the heater stage.
In this stage, TVS can be used to verify whether the bonding portions (electrodes, leads, etc.) of the preheated work (lC chips, lead frames, etc.) are in proper condition of temperature distribution.
In this way, TVS is widely used for the quality control of Wire Bonding.
